title: Cutaneous ciliated cyst in the subcutaneous area.
abstract: A 25-year-old woman was seen for a painless subcutaneous mass of 2 years duration. On excisional biopsy, a collapsed cystic structure lined by stratified, ciliated, columnar epithelium was noted. These linning cells did not produce mucin. Immunohistochemical staining for progesterone receptor, estrogen receptor and epithelial membrane antigen was positive, whereas it was negative for carcinoembryonic antigen. Findings were consistent with cutaneous ciliated cyst (CCC). CCCs are rare, predominantly occurring on the lower extremities of young women. Most of them have been regarded as Mullerian remnants. A case of a CCC in the subcutaneous area is reported.
